Input A, B, C, D Frequency Measurement Accuracy Test
Note
The test steps for channel C and D are only for the 4-channel models.
To test the frequency measurement accuracy:
1. Connect the Test Tool to the 5502A. See
. Do not use 50
Ω
terminations.

Reading 3, on C, Hz
Reading 4, on D, Hz
3. Use
j
and
k
to select range 100 mV/div for A, B, C and D.
4. Use
V
to select the required time base setting.
5. Set the 5502A to source a sine wave according to the first test point in
.
Because the 50
Ω
termination is not applied, the 5502A leveled sine wave output amplitude
can vary.
6. Observe reading A, B, C, and D and check that it is within the range shown under the
appropriate column.
